For what it is worth, I got a minute tear in the bottom of one of my halcyon large shopping bags two or three years ago. I did contact customer service, and there was not a good repair for it, but the amazing thing is that I have continued to use the bag for heavy shopping loads since, and the tear has not spread, and the bag continues to handle heavy loads just fine.

I am amazed at the durability of these bags!

I use Tenacious Tape as linked above. Cut it with rounded corners. Apply it in a warm environment and press it firmly. Let it cure for 24 hours. I've never had Tenacious Tape peel, except when intentionally removed.

I think that the Black Nylon is the toughest and appropriate for 400D Halcyon and high wear spots like bag bottoms. Sage and Off-White Ripstop are ideal for lighter fabrics and technical clothing like shell and puffy jackets. I've patched many a tent hole with the Ripstop Tenacious Tape, even mosquito netting.

Stay away from Clear at all costs, it is substantially less strong and only really appropriate for vinyl/PVC/urethane type materials!

Carrot, in your experience, how difficult is it to remove Tenacious tape intentionally? Does it leave a residue, and can you use the tape to reinforce a bag in high wear areas?
I would suspect that for Tom to "repair" Halcyon, they would need to replace the whole damaged panel.

Tenacious Tape is designed to remove cleanly so that jackets, bags, etc, can be properly patched at a later time. On items I’ve patched it’s never been a question- the patches have been strong enough I haven’t even considered taking them off even through multiple laundry cycles and exposure to weather.

I think that black Tenacious tape would be good for reinforcing high wear areas, but I think that wear and tear is a natural experience for our things. I also don’t mind wear and holes, but I do patch things when able because I assume most holes are likely to get bigger with additional wear.

I can’t speak for TB as to how an item might be patched or repaired. I suspect that wear items like zippers are stitched in a way that makes them more replaceable but some fabric panels may not be replaceable at all.
